CAR ROOF.

Application filed October 14, 1924. Serial No. 7 423,521.

This invention relates in general to improvements in freight car roofsand more particularly to improvements in the class of car roofs usuallydesignated as outside metal roofs, which outside metal roof is movablyor flexibly positioned on the car so as to cover the wooden sheathing orinside Wooden roof of the car; and objects of the invention are theprovision of a metallic roof capable of movementin harmony with themotion of the car without the neoessity of providing mullions to preventthe roof from shifting; the provision of anchors for such car roofswhich are not exposed to the elements and which are arranged to hold thesheets from upward movement and from too great longitudinal movement;the provision of a roof which is capable of simple manufacture at areasonable cost and which can be readily applied on the car without thenecessity of specially skilled workmen and which when so applied will beweathertight and not require frequent repair and replacement; and suchother objects and advantages of the invention as are found to obtain inthe structure hereinafter set forth and claimed.

In the accompanying drawings forming a part of this specification, andshowing, for

purposes of exemplification, a preferred form and manner in which theinvention may be embodied and practiced, but without limiting theclaimed invention spec fi cally to such illustrative instance or1nstances Figure 1 is a top plan view of a car roof embodying theinvention, part-s belng broken away for better illustration.

On the drawings, 10' indicates the wooden side plates that extendlongitudinally of the car and 11 is the inside wooden roof sheathing. 12is the side sheathing of the car, the upper edge of which is flush withthe upper surface of the adjacent side plate. 13 is the side fascia, theupper edge of which is flush with the upper surface of the sidesheathing 12. The outer edge of the roof sheathing 11 extends over theside sheathing and protrudes over a portion of the side fascia 13. Theeaves edges of the roof sheating 11 are gained out at 14 to receive ametallic flashing 15 whose inner edge terminates in an upwardlyprojecting open return bend hook 16 whose upper surface is below theplane of the top of the ungained roof sheathing and the flashing isflanged downwardly at 17 to enclose the edges 18.

of the roof sheathing and is then bent outwardly at 1.9 over the topsurface of the side fascia where it terminates in a depending flange 20secured to the outer side of the side fascia.

Roof sheets 21 are disposed on opposite sides of the ridge 22 of theroof, said roof sheets having inverted U-shaped ridge flanges 22 lappedone over the other and side flanges 23, said side flanges 23 c0nsistingof an upwardly extending inwardly inclined portion 24 terminating in adownwardly extending portion 25 spaced from the pprtion 24 and the mainbody 26 of the roof s eet. point 27 short of the eaves edge of the roofand the unflanged portion of the sides of the roof sheets are extendedto form extensions or ears 28. The eaves edges of said roof sheets areflanged downwardly at 29 andterminate in an outwardly pressedlongitudinally extending rigidifying head 30 that is arranged over theoutwardly extending portions 19 of the flashing but out of contacttherewith. The ears 28, flanges 29 and beads 30 of adjacent roof sheetsare lapped one over the other at 31. Roof anchors 32 are provided, inthe present instance, secured on the flashing at the eaves edge of thecar, one between the sides of two adja cent roof sheets. These anchorsconsist of a top web 33 having depending inwardly inclined sides 34spaced from each other to provide a space 35 and said sides terminate inoutwardly extending flanges 36 spaced from each other and said flanges36 are secured to the roof sheathing by means passing through theapertures 37 therein, One

Said side flanges 23 terminate at a end of each of said flanges 36 isbent downwardly at 38110 fit against the flange 17 of the flashing andis then bent outwardly at 39 to fit over the portion 19 of said flashingand the portion; 39; terminates; in a. depending flang 40 that issecured to the side fascia. The lower ends of the sides 34 are cut awayto provide slots 41 through which the lapped extensions or ears 28 passand are loosely confined therein 30 that the roof sheets may partake ofproper movement and yetbe efl'ectivcly held down on the roofsheathingand prevented from shifting.

Side seam caps 42 extend from ridge to eaves, said caps being ofsubstantially tubular form and having curved sides 43 inwvardly turnedat their lower ends and terminating in' upwardly ext-ending flanges 4A:spaced froin each other-and from the sides 4l3 and when assembled on theroof, the flangesl; are arranged in the spaces prow'iclcd between theportions 24 and 25 of the side flanges 23 of thereof sheets. Thesesidesea-m caps enclose the sides of adjacent sheets and the anchorarranged therebetween at the eaves-of the roof and as they are notconnected with the anchors, the anchors may bepositioned on the roofsheath- 4160f the side'seani, caps.- 42, wooden root sheathing l-1-longitudinally extending ridge pole 52:

I'From' the foregoing it will be apparent thattlieroof sheets aresecurely held'downin;:plwce' in weathertight condition without requiringwoodenmnllions or outside clips andithat' thesid'e seamjcaps and theanchors constitute the sole means between. the sheets forspacing andholding the sheets in rela;-

l heninventiom as, hereinaboveset forth is embedie'd; i-n 'aparticularform of construction but, may be variously embodied within the scoperot" the,claimswhereinafter made.
